This is a good day trip. Great ocean views, beaches, and hiking.
This is a good day trip. Snohomish is a cute little town along the river. With some nice restaurants and bakeries.
See where we live! Sarah and I actually live in Issaquah, WA. About 30 min east of Seattle. There's a bunch of hiking and outdoor activities, a cute little downtown, and the Snoqualmie Falls.
A great add-on if you want to spend a day before or after in the city. Spend some time exploring Seattle! If you're in the city we recommend visiting Pike's place, walking along the waterfront, and taking the ferry over to Bainbridge Island (personal favorite).
This is more of an extended trip if you want to add a day or two to your visit. Take a ferry out to the San Juans! From Anacortes you can hop on a ferry and head out to any number of islands for an extra day or two.
Another extended option if you want to drive up into the mountains. Leavenworth is a fun place town to visit. The whole town is theme like a Bavarian village. It's fun to check out the town and there's lots of good outdoor activities in the area as well.
